👉 A trigonatron, also known as a tritium laser, is a type of laser that uses tritium (Kr-4) as its primary source. Tritium is a highly radioactive isotope with a half-life of 273 days and can be used to create ultrashort pulses for the production of light and other types of radiation. Tritium lasers have been used in various applications, including medical imaging, spectroscopy, and particle physics.
